or container opening at all times until fueling is
complete.
DANGER
In certain conditions, fuel is extremely flammable
and highly explosive. A fire or explosion from fuel
can burn you and others and can damage property.
• Fill the fuel tank outdoors, in an open area,
when the engine is cold. Wipe up any fuel that
spills.
• Never fill the fuel tank inside an enclosed trailer.
• Never smoke when handling fuel, and stay
away from an open flame or where fuel fumes
may be ignited by a spark.
• Store fuel in an approved container and keep it
out of the reach of children. Never buy more
than a 30-day supply of fuel.
• Do not operate without entire exhaust system
in place and in proper working condition.
Filling the Fuel Tank
1. Park the machine on a level surface.
2. Using a clean rag, clean area around fuel tank cap.
3. Remove cap from the fuel tank (Figure 20).

1. Fuel tank cap
4. Fill the tank until the level is to the bottom of the
filler neck with diesel fuel.
5. Install fuel tank cap tightly after filling tank.
Note: If possible, fill the fuel tank after each use.
This will minimize possible buildup of condensation
inside the fuel tank.

Checking the Tire Pressure

Service Interval: Before each use or daily
The correct air pressure in the front tires is 50 psi (345
kPa) and the rear tires is 30 psi (207 kPa) (Figure 21).
Important: Maintain pressure in all tires to
ensure a good quality-of-cut and proper machine
performance. Do not under-inflate.
Check the air pressure in all the tires before
operating the machine.
Checking the Torque of Wheel
Lug Nuts
Service Interval: After the first 10 hours
Every 250 hours
WARNING
Failure to maintain proper torque of the wheel nuts
could result in failure or loss of wheel and may
result in personal injury.
Torque the front and rear wheel nuts to 70 to 90
ft-lb (95 to 122 N⋅ ⋅ ⋅ m) after 10 hours of operation.
Torque every 250 hours thereafter.

Adjusting the Height-of-Cut

The height-of-cut is adjustable from 1 to 6 inches (25
to 153 mm) in 1/2 inch (13 mm) increments. To adjust
the height-of-cut, position the castor wheel axles in
the upper or lower holes of the castor forks, add or
remove an equal number of spacers from the castor
forks, and adjust the rear chain (front deck only) to the
desired holes. The higher heights of cut are attained by
repositioning the deck caster arms to the lower set of
holes on the deck mounting brackets.
Front Cutting Unit
1. Start the engine and raise the cutting units so that
the height-of-cut can be changed. Stop the engine
and remove the key after the cutting unit is raised.
